In an interview with Chile's Channel 13, the mayor of Arica, just north of Iquique, said the city had only seen small waves, "nothing that we would call a tsunami."

Mahmud Aleuy, Chile's sub-secretary of the interior, said during a televised press conference the Chilean government has not received any reports of injuries or serious damage.

The government is asking the entire coast, however, to evacuate, which has caused some traffic problems, Aleuy said.

He added that the northern part of Chile had received a first tsunami wave, but was expecting a second one, because the sea had receded.

The last big earthquake that affected Chile was a powerful 8.8 magnitude quake that struck near Concepcion in 2010.
